- DE 10 2012 213 273 A1 describes an energy storage device for a vehicle. Generally, energy storage devices are used for mobile power, backup power, and the like.
- An object of the present invention is to provide a unit, referred to as accumulator Energyspei ⁇ chervorraum with an optimized heat dissipation in encompassed by the accumulator battery cells.
- the invention proposes a new type of heat dissipation from accumulator units hereinafter referred to as rechargeable battery cells - the so-called secondary cells acting as energy storage cells - in particular rechargeable battery cells in the form of round cells, and in a particular embodiment an optionally combinable new type for efficient current conduction.
- tion in from the accumulator included in front of the battery cell in particular ⁇ sondere one battery cell in the form of a circular cell, or a group of such battery cells. This is done by the cell contacting, namely an electrically conductive ZellWallettechnik for power management of and / or to the respective battery cell, takes place exclusively from one side.
- the opposite side is available for pure heat dissipation.
- the heat can thus be transported by the shortest route to or to a cooling surface or the like.
- the battery cells are held in position via a cell holder acting as a carrier.
- an accumulator module functioning as an energy storage device having the features of claim 1.
- an accumulator in the interior of a housing of Akkumula ⁇ Call Module at least one equippable with a plurality of battery cells carrier can be placed and an operable accumulator is in the interior of the housing at least one tipped with a plurality of battery cells carrier sheet plate-.
- Each battery cell is electrically contacted in the carrier only on one side and the or each equipped with rechargeable batteries carrier is placed in the interior of the housing of Akkumulatormo ⁇ module in a free end surfaces of the battery cells thermally coupled to a heat sink shape, for example, acting as a heat sink side surface of the housing.
- the housing acts asdekör ⁇ per example.
- the housing or the relevant side surface of the hous ⁇ ses receives the heat energy derived from the battery cells and outputs them, for example by convection to the environment. Additionally or alternatively, by means of the housing or the relevant side surface of the housing, a targeted heating of the battery cells can take place.
- the peculiarity of the accumulator module proposed here consists in the summary of the only one-sided electrically contacted battery cells in the carrier.
- Battery cells whose outer surfaces act as poles are conventionally ren, known at both ends, so for example, battery cells in the form of round cells at their two end faces / faces, contacted.
- the hereinafter sometimes briefly only as a one-sided contacting designated only unilateral electrical contact of the battery cells allows a particularly space-saving shape of the electrically conductive connection of a plurality of battery cells and because of the lack of necessity, printed conductors of an end of a Ak ⁇ kuzelle into the region of the To have to provide opposite end, even a high packing density of a plurality of battery cells, as summarized by the approach proposed here in an accumulator module.
- the short conductor lengths and few material transitions lead to only a low power loss.
- the one-sided contact and the possible combination of the battery cells also means that all the battery cells of a carrier can be placed therein in the manner described above. Said one-sided contacting does not refer not ⁇ maneuverable to a single geometric outer surface of the battery cell jewei ⁇ time / round cell. Rather, the term contacting einsei ⁇ refers to one of the other along a
- the one-sided contact with it basically on the top or bottom surface of the round cell limited by, for example, concentric sections of the lid or bottom surface as Po ⁇ le act.
- the one-sided contacting can but the top or bottom surface and a cover or bottom side portion of the lateral surface concern, on the one hand by a portion of the top or bottom surface, and on the other hand a cover or base side portion of the jacket surface ⁇ as Poles act.
- a cover-side section of the lateral surface of a rechargeable cell is a cover surface closing surface section; a bottom-side portion of the lateral surface of a rechargeable battery cell is corresponding to a surface portion adjoining the bottom surface.
- the free ends of the rechargeable battery cells which are only electrically contacted on one side, protrude beyond the carrier, pointing in the same direction, and the free end faces of the rechargeable battery cells are in one plane or at least substantially in one plane. Since the free ends of the rechargeable battery cells, which are contacted only on one side, protrude beyond the carrier, all point in the same direction, and the free end faces of the rechargeable battery cells are in one plane or at least substantially in one plane, the result is to a certain extent an end plane which is indirectly or can be brought directly into contact with a heat sink or the then acting as a heat sink housing of the accumulator module.
- the face plane ensures that all Akkuzel ⁇ len a wearer of the cooling (or warming) participate.
- two carriers fitted with accumulator cells can be fixed in the housing of the accumulator module by means of at least one spacer, and this fixation causes the free end faces of the accumulator cells placed in the carriers to abut against the housing on the inner surface of the housing for heat dissipation.
- the fixation of the carrier in the housing and on the other hand causes the thermal coupling of the battery cells to the housing.
- the at least one spacer spreads the two carriers apart in the housing and presses the battery cells placed in the carriers against the inner surface of the housing.
- this has an insulator between the free end faces of the battery cells and an inner surface of the housing, wherein for the thermal coupling of the free end faces of the battery cells to the housing, the free end faces of the battery cells rest on the insulator and the insulator is in turn connected to the inner surface of the housing, for example by gluing.

- the engaging in such constrictions tabs are aligned transversely or substantially transversely to the central longitudinal axis of the battery cells.
- the contact forces engaging in the constrictions Consequently, the battery cells fix in the axial direction.
- the contacting of the battery cells resulting from engagement in the constrictions thus fulfills a dual function. On the one hand, there is a secure, electrically conductive contacting. On the other hand results in a mechanical contact, which leads to an axial fixation of the battery cells.
